Specification of Letters Patent.

Application filed April 11, 1914. Serial No. 831,289.

To all ivhom it may concern Be it known that I, JOHN F. OCoNNoR, a citizen of the United States, residing at Chicago, in the county of Cook and State of -Illinois, have invented a certain new and useful Improvement in Draft-Rigging for Railway-(Jars, of which the following is a full, clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part' of this specification.

My invention relates to improvements in draft rigging for railway cars.

The object of my invention is, to provide a draft rigging of simple construction and efiicient operation.

In the drawings forming a part of this specification, Figure 1 is a side elevation,

cated by the. numerals 66.

. registering with each other.

partlyin vertical longitudinal section, of a draft-rigging embodying my invention; Fig. 2 is a horizontal section taken on line 2-2 of Fig. 1; Fig. 3 is a cross section taken on line 3-3 of Fig. 1; Fig. 4 is a vertical 1on gitudinalsection showing the position of the parts when the draft rigging is in full buff, and Fig. 1 showing the parts in normal position.

Referring to the drawings, the numerals 55 represent center sills or parts of the. car underframing to which the draft members are secured. The draft members are indi- The draft members preferably consist of channelshaped members, to the flanges whereof are secured the upper and lower transverse cover plates 7 and 8, respectively. In preferable construction, a reinforcing member 9, preferably an'angle-iron, is longitudinally secured to the'upper outer edges of the upper cover plate 7, and is suitably engaged to the adjaoeutoenter sill 5. The upper and lower cover lates 7 and 3 are each provided with a vertical opening. 10, the said openings The portion of the cover plates forming the forward ends of these openin'gs constitute the front stop-shouiders. 12-12, and the portions of the said cover plates. forming the rearward end of said opening constitute the rear stopshoulders 1313. Inpreferable construction, the stop-shoulders'so formed are rei {Qrced by outwardly disposed members '1 f .14, preferably angle-irons mounted at the front and rear edges of the openings 10 lower, and 16 the rear follower. Between j thefollowers is mounted a compression resisting member 17, consisting preferably of an upper set of s rings 18, and a lower set of springs 19. ach set of springs (comprlses preferably an outer spring 20 and an inner spring 21' nested therein. The followers are each provided on their inner faces with upper and lower bosses 22 and 23, respectively, about which the ends of the sets of springs are seated. Passing be" tween the followers and between the upper and lower sets of springs is a key 24, secured at its ends within the-draft members 66.

and claims, is meant not only the U-shaped type of yoke shown in the drawings, but all equivalent means serving a similar function for connecting'the draw bar-withthe rear follower so as to pull the latter forwardly underdraft, such means sometimes taking the form of links and keys. The ends of the key 27 pass through longitudinally extended slots 29 in adjacent portions of the draft members 6. .I reinforce the draftmembers by providing a separable arm 30 for each, secured to the draft member by means of the rivets 31-31. The said arms 30 are preferably mounted on the outer faces of the draft members as shown in' the drawings. The saidv armsare each provided with perfiorations 33 for the key 24, and 34 for the ey 27. The key 24 is secured at its ends within the draft members, andis prevented from being accidentally displaced preferably by the bolts 35-35 passing therethrough and through adjacent portions of the arm J36 'The limbs 3636 of the yoke are pro vided with transverse perforations 37 through which the key 24 passes, the perforations or slots 37 being rearwardly extended to permit the movement of the yoke upon the key 2- 1. In preferable construction, the slots 37 being of such length that whenthe forward ends of the slots engage against the front edge of the key 24, and the rear follower is in engagement against the rear StOP-S UldBr, the rear follower will also be in engagement with the rear end of the yoke. Thus in bufling movement of the gear, the rear follower is held against rearward movement by both the rear stop-shoulders and through the yoke by the key 24.

On'forward movement of the drawbar,'

the slots 28 in the yoke, the draw-bar 26' directly engaging the front follower and compressing the compression resisting members against the rear follower 16, which is stopped against rearward movement by the rear stop-shoulders formed as hereinbefore described, and also by the draft yoke, which 4 is held against rearward movement bythe key 24.

against forward movement by the I claim:

1. In a draft rigging for railway cars, the combination with draft members, a drawbar and draft yoke connected to the drawbar, of followers, a compression resisting member mounted between the followers, a key secured at its ends in the draft members and passing between the followers, and cover plates, the cover plates being provided with openings to receive the followers and compression resistingmembers, the portions of the cover plates defining the front and rear ends of the said openings constituting stopshoulders for the followers said key supporting the compression resisting member.

2. In a draft rigging for railway cars, the combination with draft members, of upper and lower flat plates secured to the tops and bottoms of said draft members, said plates being provided with vertically alined openings, said openings being narrower than the distance between the draft members and the front and rear edges of said plate defining said openings constituting front and rear stop shoulders, reinforcing members se cured to said plates and located flush with the front and rear edges of said openings, said reinforcing members being shorter than the distancevbetween .the draft members, followers mounted within said openings, a stationary key passing between the followers and shock absorbing means located between said followers, said key acting as a limiting stop for said followers;
